GSC (surface water) ion chromatography/ conductometric (Cl, Br, NO3, SO4, PO4)

Geological Survey of Canada, surface water; ion chromatography/conductimetric(Cl,Br,NO3,SO4,PO4)

General Methodology:

Determined by ion chromatography/conductimetric analysis using a fully automated Dionex Model 12 chromatograph.  The samples were initially filtered through 0.45 μm Millipore filter paper and injected onto the columns.  An anion exchange resin was used as separator followed by a high capacity cation exchange resin as suppressor in an eluent of 0.0024 M NaHCO3/0.003 M Na2CO3.  A chart recorder was used to check the peaks for possible interference.
